"Wanted: Someone to go back in time with me," stated the ad, which co-star Johnson ("New Girl") reads aloud in the film's trailer. "This is not a joke. You'll get paid after we get back. Must bring your own weapons. Safety not guaranteed. I have only done this once before."

Of course, there's much more to "Safety Not Guaranteed" than just the prospect of time traveling: Plaza's Darius, a magazine intern, forges a relationship with the ad's author, Kenneth (Duplass). Is the eccentric supermarket worker completely insane? Kinda insane? Not insane at all? Those are the questions the film attempts to answer, all with a sweet-sad tone reminiscent of Wes Anderson's best work.
